Hi,
Thank you for posting your question in the Microsoft Community.
I understand that you want to rip the DVD. I will try to help you with this.
I would like to let you know that when you copy music, pictures, and videos from your PC to a blank CD or DVD, it's called "burning”. When you copy music, pictures, and videos from a CD or DVD to your PC, it's called "ripping”. You can use Windows Media Player in Windows 8.1 to do both.
